Robin and I were just starting to go at it...I was entangled in her legs and quickly working my way towards her clit. All of a sudden, she froze and yelled, "Lynn, what are you doing?"
I looked up to see her daughter standing in the doorway. She seemed to be watching and, very, into what we were doing; she had a hand buried in her shorts. My eyes were drawn to her body...the toned abs, a cute belly button and a very, tight-fitting t-shirt. You couldn't miss the breasts that filled out that shirt; her nipples almost pushed through the fabric.
"I'm...I'm just watching...Brian's not here and I'm really horny. I need some release...and...I sort of ...wanted to see him naked."
Over the past year or so, Brian had been her on-and-off boyfriend. Unless she asked, I never intervened in anything, relating to Robin's kids; but this seemed to warrant a reply, "Lynn, I understand needs...I'm always horny, but why would you possibly need to see me naked?"
Lynn blushed and looked down; Robin bluntly replied, "Rob, I swear you can be so slow or oblivious... FYI...Lynn thinks you're hot." I remember just shaking my head and saying nothing more. At that point, I really didn't know what to say...it seemed like I was treading on dangerous ground. Lynn was a looker...she was clearly Robin's daughter...bold, intelligent and absolutely gorgeous! She was going into her senior year of college and applying for grad school. She was athletic and had the same hot body that her mother had. On the volleyball team, at school, I think she lettered in swimming, track & volleyball in high school.
Robin seemed a little agitated and nervous. She was rambling a bit and went on to reason her way through the situation, "Rob, I think we should do this. Now that they're both older, I try to maintain an open relationship with my kids...I really try. They need to know about healthy relationships, including sex. I think this's a teaching moment...we should really go ahead and finish what we were doing...just let her watch. And, I'll just throw this out...I'm in the same boat with Lynn...I'm horny & need release."
"What do you say...it's up to you?"
A little surprised with the conclusion, I looked over at Lynn, then wrinkled my face at Robin and replied, "What? Really?" Any doubt was probably misguided, since we had some seriously wild sex, in the past. I guess a precedent had been set...fuck, we have sex everywhere and every way we can...we had a threesome, not long ago. I was just apprehensive and not sure this was the thing we should be doing in front of her daughter, but fuck it...we were in the middle of sex, almost, and very, very horny. I guess horny usually wins!
"Okay...here goes." I stood up to pull my shirt off and Robin slid her hands over my chest & belly. At first, it was just some sexy exploring, but when she slipped her hand into my pants, I knew she was serious...we were actually having sex, with her daughter in the room. I did notice Lynn was intently watching me strip; and her gaze wasn't what I'd call subtle...she was visibly lusting over me, her mom's boyfriend. I smiled nervously and played along with things; I slipped my pants off to reveal a cock, half-hard, and arching outward.
I didn't know if I was comfortable with this concept of "Show and Tell," but I quickly realized that it felt damn good to feel a hot mom and daughter, exploring every detail. I watched as Lynn's eyes darted lower, focusing on my dick, pulsing its way to a full erection. She walked towards me and I stroked a couple times, before offering it to her.
"Oooh, its thick," said Lynn. "Can I touch?"
Robin said, "Go ahead, Honey...feel it...explore it. It's okay."
She reached out to wrap her hand over it. Now fully erect, she carefully gripped the shaft and her hand felt cooling and soothing. "Mom, you weren't lying...he's big & hard...I can hardly close my hand!"
Robin piped up and declared, "Honey, it's almost 9 inches and there's room for the two of us."
I shot another look over at Robin that expressed surprise...and confusion, "The two of us? What the hell do you mean by that...what the fuck is going on?"
She shrugged, flashed a little smile and said, "I don't know...you'll see."
Her flippant reply should've been a more immediate concern, but at the time, I was disturbed, or maybe embarrassed, that she would discuss our sex life, or my cock, with her daughter. "And...you've discussed my cock with Lynn?"
"Just a little bit...it's girl-talk...and I'm proud of you...I'm proud to have you as my boyfriend."
I turned away and Lynn just continued on like she hadn't heard a thing and traced the rim with her finger. "I really like the head...it's a lot bigger than Brian's,"
Still holding me, she wrapped her other hand over the head, and felt the pre-cum oozing, from the tip. "Ooooh, you're wet...it's wet," she squealed. She pulled her hand away, only to replace it with a finger that she rubbed over the tip, coating the head with warm juice. When she pulled her finger away for a closer look, a sticky strand trailed and tethered it to my swollen dick. She glanced over at her mom, who told her to give it a try. Lynn shrugged, and tentatively stuck the finger into her mouth "Mmmm, that is yummy...you taste good."
"Now, you can sit there and watch us, Honey...Rob & I need to finish things and you need to learn about good, healthy sex...sex that satisfies both of you."
I tried to lighten things by saying, "Lynn, just remember...it's important to have sex all the time...frequency and duration are essential."
